A carotid stenting system has demonstrated significantly low stroke rates in a recent trial, marking a milestone in carotid artery stenting. This innovative system, Neuroguard IEP by Contego Medical, received FDA approval in October, paving the way for improved patient outcomes.
Dr. D. Christopher Metzger, a leading vascular expert, presented the findings of the PERFORMANCE II trial at the Society for Cardiovascular Angiography and Interventions Scientific Sessions. The trial, conducted across 32 sites in the U.S. and European Union, focused on patients with carotid artery stenosis who were at high risk for adverse events from carotid endarterectomy.
During the trial, the carotid stenting system demonstrated exceptional results. The primary endpoint of death/stroke/MI at 30 days and ipsilateral stroke at 1 year occurred in only a small percentage of patients. Notably, the rate of ipsilateral stroke between day 31 and 1 year was remarkably low, with no cases of major stroke, neurologic death, stent thrombosis, or clinically driven target lesion revascularization at 1 year.
At the 2-year mark, the system continued to show positive outcomes, with no major stroke incidents reported. The overall target lesion revascularization rate and in-stent restenosis rate were also notably low at 2 years.
Dr. Metzger highlighted the unique design of the Neuroguard integrated system, emphasizing its role in protecting patients during critical phases of carotid stenting. The system’s advanced features, including a closed-cell stent, a 40 µ filter, and a postdilation balloon, contribute to reducing periprocedural stroke risks.
Reflecting on the broader impact of this technology, Dr. Metzger noted that advancements in carotid stenting have made the procedure more accessible. He predicted a potential increase in the adoption of this system, particularly as it offers flexibility for different stenting approaches.
The successful outcomes of the carotid stenting trial underscore the importance of ongoing innovation in vascular interventions. With the Neuroguard system setting a new standard for stroke prevention in carotid stenting, patients with carotid artery stenosis may benefit from improved safety and efficacy in vascular procedures.
As technological advancements continue to shape the landscape of cardiovascular interventions, the field of carotid artery stenting is poised for further evolution. The integration of cutting-edge systems like Neuroguard signifies a significant step towards enhancing patient care and reducing the burden of stroke risk in high-risk populations.
